Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78978, here are decompositions:

37 + 78941 = 78978
59 + 78919 = 78978
89 + 78889 = 78978
101 + 78877 = 78978
139 + 78839 = 78978
181 + 78797 = 78978
191 + 78787 = 78978
197 + 78781 = 78978

Showing the first eight; more decompositions exist.
